Re-do the enhancing magic formulas to scale properly, add formulas to spells that currently don't make use of magic skills. Bam, problem somewhat corrected. If the job doesn't have native skill it won't be nearly as useful as a proper mage job using it. This still leaves the problem of Scholar subbing all of our goodies, but overhauling and adding formulas to some of the enhancing magic spells is long overdue regardless.
